LOCK;

To all whom it may concern:

Be it known that I, LEOPOLD A. WISE, a citizen of the-v United States, residing at New York city, in the 'countyof New York and State of New York, haveA invented certain new and useful Improvements in Locks, of which the following is a'specication, reference being had to the accompanying drawings.

My invention relates to improvements in locks, and particularly to improvements in combination locks adapted for use upon doors; and an object ofmy invention is to provide ,a lock of the character just described which will be simplein construction, comparatively cheap in manufacture and most eiiicient, secure and durable in use.`

In the drawingsy illustrating the Yprinciple of my invention, and the best mode now own to me of Figure 1 is an edge provided with my of the outside lof the same; Fig. 3 shows the inside of the door illustrated in Figs.` 1 and 2;

View of a por-tion of a door Figs. 4, 5 and 6 show the inside look mechanism corresponding to three different positions of the latch-locking spindle; Figs; 7, 8 and 9 are outside end views corresponding to Figs. 4, 5 and 6 Fig. 10 is a section on the line A-A of Fig. 1;Fig. 1-1 is afront view of the tumblers detached g Fig. 12 is a section on the line B-B of Fig. 1 1; Fig.` r13 is a perspective showing the bolt mechanismand its attached parts; Fig. 14 is a plan ofthe bolt mechanism, the tumbler-dog being in` engagement with the tumblers Fig. 15 is a section on line C-C of Fig. 14 and shows different positions of the tumbler-dog; Fig. `16 is a detail showing the locking device for the bolt; Fig. 17 is a detail of the actuating spindle and'Fig. 18 is an end same looking in the direction vof view of the the arrow D in Fig. 17.

The lock is provided with a housing c' and cover plate b. Near the center ofthe back of the housing c there is formed an annular flange or hub c .which projects inwardly.

Theback of the housing a is further formed l with an inwardly-extending stud d and vtwo which is slidably the latter is beveled and applying that principle, j

The coil spring inwardly-projecting guide plates e, between l `b Patented May 11, 1909. l serial No. 458,601. i

i projects through an opening g in vone side of the` housing c. 4,The inner'end of the bolt or latch fis formed with a socket h (Fig. 13), in which is iitted one endof a coil spring i, the other end 'of which is fastened to the stud d. .t tends to force the bolt or latch f outwardly. Into the central hole of `the hub or annular flange c is screwed one end of a lsleeve j, the other end of which screws into a socketed bearing or sleeve c The sleeve y' is formed with an annular flange m on its exterior andthe socketed bearing 7c is formed with a similar annular iiange n on its outer wall. Upon the outer end of the socketed bearing or sleeve 7c is screwed a ring 0, between which and the flange n is rotatably mounted the initial tumbler p. Between the annular ilange or hub c and the annular flan e 'm vis rotatably mounted the final tumb er q (Fig. 12), and between the flangesm and 'n isrotatablyfmounted the intermediate tumbler r. The initial tumbler p is formed with a series of holes s, arranged on a circle having for its center the center of the tumbler (Fig. 11).

Through a hole in the outer end of the socketed bearing 7c there projects, into the sleeve. y', the inner end of the actuating spindle t, which carries the driving disk u formed witha pair of driving pins o, which are adapted to engage a pair of the holes s. The actuating sp` dle t is formed with a longitudinal series of holes w each of which is adapted to receive. the inner end of apin x by which the disk u is fastened tothe spindle t. The position of the driving disk u may be varied to adapt the lock for use with doors y of different' thicknesses, as is shown by the dotted lines in Fig. 12. Y

On vits face opposite. to. the. intermediate tumbler 1*,.the initialtumbler p is formed, with a stud .c adapted to engage the stud 2 which projects-'from the intermediate tumbler r toward the initial tumbler p and the nal tumblerv g is formed on its face opposite to the intermediate tumbler r with a stud 3 which is adapted to be engaged bythe stud 4 which projects from the intermediate'tu'mler r toward the final tumbler g. The initial tumbler p is formed with a peripheral notch or recess 5, one wall of which is curved at its junction with the circumferential wall turning the locking spindle 19, be interof the tumbler, asis shown at 6 in Fig. 11. The intermediate tumbler r is formed with a .peripheral notch 7, as is shown in Fig. 11;

and the inal tumbler g is formed with a peripheral notch 8, similar to the peripheral notch 7 of the intermediatetumbler r. The latch f is formed with an inwardly extending arm 9 from which projects a pair of iingers 10. i/Vhen the latch f is in its locking position, one of the lingers 10 lies over the driving disk u and prevents the spindle t from being withdrawn; but when the latch is pushed inwardly until the line 11 registers with the wall of the opening g in the housing a, the lingers 1() assume the position shown by the dotted lines in Fig. .el and thereby permit the withdrawal o'lI the actuating spindle t for the purpose of changing the combination.

Pivotally mounted upon the inner face of the latch is a tumbler dog 12, the head of' which is formed with a cam face 13 (F ig. 13). The cam portion 13 of the tumbler dog is adapted to enter the notch or recess 5 in the initial tumbler p, while the other portion of the head of the tumbler dog is adapted to lie in the notches 7 and 8 in the intermediate and final tumblers r, g. that in turning the initial tumbler, the latter may be turned so far that the cani portion 6 oi the wall oi the recess 5 will act upon the cani face 13 of the head of the tumbler dog 12, so as to force the latter out ol" the notches 5,7,8 (ing-.15).

Above the opening y, the housing a is formed with a recess 14, the bottom wall of which is formed with a central hole through which extends the threaded shank 15 oi' a screw, the disk-like head 16 of which lies in the recess 14 and is formed with a diametral lug 17 (Fig. 16). The threaded shank 15 screws into the socket 1S in one end of the locking spindle 19, the other end 20 of which is journa ed in the housing (L. rlhe latch f is formed with a channel 21 and the latchlocking spindle 19 is formed with a lockingin 22; and when the latch f is forced inwardly until the channel 21 lies in the path of rotation of the locking-pin 22, the latch may be locked in that position by merely turning the locking spindle 19 by means of the lug 17. It will be observed that the latter lies in the recess 14 and is thereby shielded from being tampered with readily. Fig. 6 shows the latch f locked in its innermost position and in this position it will be observed that one of the fingers 10 lies over the driving disk u and thereby prevents the removal of the actuating spindle t. Again, in this osition of the latch. f the door' may be readi y opened and closed without operating the lock; that is, the lock is made inactive. Upon the locking spindle 19 near its center is mounted a locking lug 23, which may, by i t will be obvious posed in the path of4 travel of the head of the tumbler dog 12. When the locking lug 23 is thrown into the position shown in F 5; that is, downwardly, and the tumbler dog is raised out of the notches, 5, 7,'8 in the tumblers and into the position shown in Fig. 5, the latch is locked in its outermost position and cannot be forced inwardly except by bringing the notches 5, 7, S into register so that the head of the tumbler dog 12 will fall into these notches, in which case by rotating the tuinblers the lat-'sh f may be drawn inwardly. ln other words, the latch f is locked against movement by persons -other than those having the combination to the lock. The locking-pin 2 and. the locking-lug 23 both serve. to limit by their engagement with the back of the housing u, the rotation of the locking spindle 1). Lines 32, 33 and 341, serve to indicate to the operator the points to which to bring the lug 17, in order that the locking spindle may have the several positions shown in Figs. Al, 5, and 6, respectively.

rl`he door yy is formedv with a cylindrical opening 25 through which extends the actuating spindle t and over the outer end oll which is placed the dial plate 26. yl`he actuating spindle t passes through a central hole in the dial plate 26 and is provided at ils outer end with a knob 27 formed with an index niark 28. The knob 27 covers the screws 31 by which the plate 2G is fastened on the door (Fig. 10).

Fig. l shows the normal position ol' the parts of the lock. when it is desirml to change the combination the latch y" is l'orred inwaidly until the line 11 registers with the wall of the opening y; in the housing u. ln this position of the latch, the fingers l() are. moved. from over the driving disk u so that the latter may be withdrawn between the ingers 10, thereigiy disengaging the driving pins i) lroin the holes s in the initial tumbler p (Fig. 12). The actuating spindle may now be rotated without rotating the tum bleis; and the driving pins 'u may be l'orred back into a new pair oi holes s, tlierrhr bringing the index mark opposite a new number on. the dial-plateil" one who does not know the combination attempts to ascertain what it and succeeds in bringing the tumbier-notches 5, 7, S into register, so that thehead ol" the tumbler-dog 12 lfalls by its own weight into these nolehes in the way that it is 4adapted :inl designed lo do, he nevertheless may liail to open the loeli: for, if he turns the tumblers until the curved poi'tifni 6 oll the initial tumbler p bears against the cam lace 13 el" the head el' the tumbler-dog 12, the latter will be raised from l out ol the notches and the mimbiuation will be lost to the party seeking it.

T he back of the housing a, is formed with a fill lll() lill l 3 ll slot 29, through which extends the shank of to connect the latter with said tumblers and a thumb-piece 30. latchf and allows the lock to be opened from the inside of the room.
